Voxomat adds a unique human-meets-machine character to your tracks. It transforms simple basslines into talkative, morphing sequences, while offering endless possibilities for non-pitched sounds like drums. Higher-pitched inputs can trigger complex harmonic shaping effects – the resulting inharmonic textures and FM-style intermodulation deliver a grit typical of Lo-Fi aesthetics. Conversely, these frequency modulation effects can also be smoothed out by using harmonically dense inputs, such as overdriven tones or overtone-rich sawtooth-based sounds. Using the plugin's modulation options in parallel opens wider sonic possibilities – for example, adding powerful chiptune effects to any source or mimicking the aggressive, harmonically shifting "tearing" sound of hard-synced oscillators. Based on the Ringotron engine, Voxomat utilizes a hybrid modulation architecture combining audio-rate modulation with resonators. FEATURES: • Complex rhythmic movement driven by an array of synced LFOs for deep, malleable modulation • Integrated envelope follower for responsive modulation • Touchscreen-friendly modulation sequencer for pitch FX control • Powerful resonant vocalizer for synth basses and all overtone-rich bass timbres • On unpitched inputs like drums, effects range from whispers to glottal textures and stronger vocal glitches • For pitched inputs, higher registers can more easily uncover robotic qualities as complex frequency relationships yield unique, inharmonic textures • The user interface is designed to blend algorithmic automation with tactile control, turning the effect into a responsive performance tool • Each preset features a set of primary performance controls pre-mapped for automation and expressive live play PLEASE NOTE: • An AUv3-compatible host is required to use this app • The plugin is designed as an audio processor and is not a MIDI note event processor or sequencer in its current form • Suported sampling rates: 44.1, 48, 96 kHz
